Cooking help for dairy allergies

Over the last couple of years, I have known that I have an allergy to milk and peanuts.  It has been interesting to observe others as they try to prepare dishes that don't involve these ingredients.  Peanuts are obviously a pretty easy thing to steer clear from (don't put peanuts in a dish and don't eat anything with peanut butter).  Milk, on the other hand, is apparently a little more tricky.  I'm not upset nor do I hold any ill will toward those who struggle to know what foods include milk; it is just simply interesting to observe.  There have been times when I have told people that I am allergic to milk, but then they will ask me if it is ok for me to have cheese or sour cream.  It's odd to me but it does take a bit to get used to ingredients that are usually used but no longer can.  I have compiled a list of things that should not be included in food that I consume if I want to have a happier stomach and nose.

Dairy ingredients
Cow's milk
Cheese
Sour cream
Butter
Ice cream
Milk chocolate (including syrup and hot chocolate mixes)
Yogurt
Ranch dressing (and any other creamy dressing)
Creamer
Whipped cream
Cream cheese
Cream of anything soup
Anything with the word "cream" in it
Anything in the dairy aisle :)

There are many foods that typically include these ingredients, and they are not usually noticed by someone not used to dairy-free cooking.

Foods typically including dairy:
Cornbread/rolls/biscuits
Pancakes
Waffles
Most cookies and cakes
Mashed potatoes
Green bean casserole (and many other casseroles)
Pumpkin pie
Pasta with cream sauce (or gravy with cream sauce)
Vegetables with butter

Suggestions for cooking for someone with a dairy allergy
1. Cocoa.  Using cocoa usually is a good substitute for chocolate, so looking for dessert recipes that use cocoa instead is a good bet.
2. Non-dairy margarine.  I generally have a tub of milk-free margarin on hand because I love it and tastes just like the real thing to me.  I will use it in any recipe that calls for margarine.
3. Non-dairy sour cream.  This stuff is pretty expensive but I use it when I am making something that absolutely calls for it- such as my cauliflower mashed potatoes.
4. Chicken broth. I make many soups, pasta sauces, and other casseroles with a chicken broth base instead of creamed soups.
5. Goat's milk cheese, such as feta.  I don't tend to like these kinds of cheeses, but they are out there in case someone wants to make a greek salad or something.
6. Brownies!  I feel as though brownies are about the safest baked dessert.  I don't think I've seen a brownie recipe with milk in it... including those already made at the store.
7. Put the cheese on the side- or on part of the meal.  A lot of times recipes simply call for cheese on top.  In that case, you can have cheese on most of the dish and just leave it off a portion of the dish.

All in all, there are many things that I can still eat as I have learned how to make substitutions.  There are a lot of meals we simply have stopped making, but we are still able to get a pretty good variety in our food.

So... thoughts?  Anything you were surprised about or hadn't thought of already?  Or is none of this surprising to those of you who read my blog?
